This made no impression on me whatsoever during the conference, but rewatching the trailer right now I'm very interested. Looks like the story might invoke emotions not unlike those created by Team ICO's games. If the gameplay is up to scratch, we should have a gem.

I think it was very fitting next to the graphically impressive, mainstream big hitters like the new Killzone and the Bungie game. I think they were basically trying to say: here's the graphically impressive stuff, but here's the quirky stuff we're known for, we haven't forgotten about it either.

Unfortunately, as history teaches us, these come out well about as often as not, so the only thing to do is wait for reviews.

I'm picking this up at launch - unless it does a genji and turns out to be terrible (warning signs were string with that one though). Cerny is at the helm so I've no worries on that and think it provides a good alternative to shooting and driving.

After watching Cerny's keynote speech, which didn't feature Knack, I think I know what's going on. He stated that it's his aspiration that early in the generation developers get good games running quickly, but the architecture affords them new avenues of exploration in later years. To that end Knack is an exercise in repurposing the GPU for physics calculations. All those bits of knack flying and bouncing about, their shapes meaning that collisions are nontrivial calculations, is Mark saying "here are the kind of tricks we expect to see later down the line."
